- Start vm: `vmc start termina`
- Open vm: `vsh terminal`
- `lxc launch images:archlinux <NAME>`
- `lxc profile set default security.syscalls.blacklist "keyctl errno 38"`
- `lxc exec <NAME> -- bash`
 
- list images: `lxc image list images:`

## Configure arch
```sh
useradd -m -G wheel <USERNAME>
passwd
New password: 
Retype new password: 
passwd: password updated successfully
```
```sh
vi /etc/locale.gen
locale-gen
Generating locales...
  en_US.UTF-8... done
  en_US.ISO-8859-1... done
Generation complete.

echo "LANG=en_US.UTF-8" > /etc/locale.conf
```
```sh
pacman -Syu
pacman -S git base-devel python reflector
reflector -c Japan -f 4 --save /etc/pacman.d/mirrorlist
```
- `lxc console arch`
```sh
git clone https://aur.archlinux.org/yay.git
cd yay
makepkg -si
```
```sh
systemctl --user enable sommelier@0      # For Wayland GUI apps
systemctl --user enable sommelier-x@0    # For X11 GUI apps
systemctl --user start sommelier@0      # For Wayland GUI apps
systemctl --user start sommelier-x@0    # For X11 GUI apps
```

```sh
As of Sept 17, 2018, xkeyboard-config breaks sommelier, consequently preventing applications with a GUI from displaying. To fix this, comment out the lines starting with <I372> and <I374> in /usr/share/X11/xkb/keycodes/evdev (using vi, vim, or another terminal text editor), then restart your container.
```

### Packages

```sh
sudo git base-devel
wayland xorg-server-xwayland 
```
